So first of all…what is a laser? It stands for “Light Amplification by Stimulated Emission of Radiation”. A diode is used to create a concentrated laser beam of light in one wavelength. The shorted the wavelength the brighter and more visible the laser beam. Stanley lasers have a standard wavelength of 635 nanometres, which is suitable for use up to 30m.
